Can't hold chlorine, all other readings good

Thanks for the input. My filter is DE. I changed it when the water was clear after spring clean up (about 10 days ago). The pressure has stayed at 12 ever since so the filter isn't removing much of anything. The water is so clear I can't imagine any algae at all being in the pool. No chlorine smell. I guess I'll have to go to the pool store and get my water tested for CC.
